Forgot to touch on this while cut n pasting the above pic's...
Most tow balls have a rating and a torque specification for the nut...that few
know about...nor try to attain...
To torque that nut properly...a torque wrench is needed...and the length is key
to the highest torque that wrench is rated for...
To tighten my tow ball nut to the specified 450 ft/lbs, a 3/4" torque wrench is
needed. Mine was over 3.5 feet long, till a buddy who borrowed it...he dropped it
and that left a dent in the head. Finally got him to pay for after getting his
wife involved...
Well...most trailers discussed here are in the +24 FEET to over 30 FEET long and
the lever arm is about 10 times longer than my old 3/4" torque wrench...
Hope some folks get that message...tighten the tow ball nut to spec...
Now add to this the fact that so many will not grease the ball. With no lubrication, the ball may seize or gall to the coupler and be rotated loose.
